Hi,all.I want to use opencv so I installed it.

However,when I import cv2,it takes a long time and failed in the end, as follows:

I tried a lot of times ,it is still the same result…It only fails when I select Slicer4.11 as a kernel but it is okay when I select python3.But I have to use Slicer as a kernel for some reason.

Is there some potential way to solve this problem?  
Thanks in advance for your help!

You need to use the python interactor of Slicer
